Building Lifecycle Management (BLM) is derived from Product Lifecycle Management (PLM) in the manufacturing sector and represents a transformative application of PLM within the engineering construction industry. The lifecycle of engineering construction projects primarily involves two key processes: information workflows and material workflows.
Before construction begins, tasks such as planning, design, and bidding revolve around the creation, processing, transmission, and application of information. While the construction phase primarily focuses on material production, this process is guided by information—such as construction drawings and related documentation—while simultaneously generating new data about materials and equipment details. During the usage phase, information guides the operation of materials and generates further data through their use.
BLM involves the digital creation, management, and sharing of information about capital assets throughout a building’s entire lifecycle, from conceptual design to demolition or repurposing after demolition. Studies conducted in the United States and the United Kingdom show that implementing BLM can reduce construction project costs by 30% to 35%.
To fully realize BLM, it is essential to rapidly and accurately capture and communicate decisions made by all project stakeholders through information. This information must be represented in a clear, three-dimensional format to minimize ambiguity. Additionally, any additions or modifications by participants should automatically update all related information across the entire project scope, a capability beyond traditional non-parametric modeling. The system must support the diverse information needs of every professional involved in the project, encompassing all geometric, physical, functional, and other relevant data. This comprehensive approach aligns with the concept of Building Information Modeling (BIM).
BIM digitally represents the physical and functional characteristics of engineering objects and other project facilities. A complete information model serves as a detailed description of the construction project and connects data, processes, and resources across different lifecycle stages. This model is accessible and usable by all parties involved in the construction project.
The Building Information Model (BIM) acts as a single source of engineering data, enabling dynamic creation, management, and sharing of information throughout the construction lifecycle. It addresses challenges related to data consistency and global sharing. Moreover, BIM provides a digital framework for architectural design, construction, and management that fosters an integrated project management environment, significantly enhancing production efficiency and reducing potential risks.
In summary, BIM forms the foundational basis for implementing BLM. To successfully achieve BLM, it is crucial first to establish a robust BIM system.
